Not sure if the UK is similar to where I lived, but they were the worst “cloud” provider I’ve ever used. Want to shut down the instance you had to recreate it with a different OS? Good luck getting it back online as they are out of capacity. Also, if you accidentally deleted one of the default network components it was impossible to recreate it without incurring a cost kind of going against anything you learned about cloud computing and “infrastructure as code”. It was a glorified GUI.
Edit: I’m just glad my current employer does not use anything oracle as their support is also famously bad.
Shelly dimmers behave like that. I might have changed a setting here and there in stock firmware but they also integrated into home assistant with an import script someone posted on the HA forums, no need for some app. The ones I have are WiFi though.
